Step 1: Open The Filtration Tank

First, you need to open the tank that holds the filtration unit. You have to find out where the filter is in your home and turn off all of the valves connected to it. This is important because if you do not do this before you replace your filter, water will start dripping everywhere when you turn the water back on. Then you can unscrew the old filter and put in a new one.

Step 2: Close The Valve

You must close all of the valves that are located on your home’s plumbing system. When you do this, there should be one open valve left, which is connected to a hose or pipe that goes to the kitchen or bathroom.

Step 3: Make Sure You Are Using Your Water Filters Properly

Make sure that your filters are being used properly. Many people don’t realize this, but there are specific instructions as to how long of a period you should go between filter changes. These can also be affected by the size and make-up of your home, so you have to check with a specialist to determine when something needs to be changed.

Step 4: Install The New Filter

Remove your old filter from the tank and then install a new one. Make sure that you are putting in a new O-ring when you are replacing it as well. You can ask your supplier of reverse osmosis water systems for an extra O-ring so that you have a backup in case something goes wrong.

Step 5: Flip The Valve Back On

Finally, you can flip the open valve on and then turn the new filter back on. You can clean off any water that has formed outside of the tank and rinse off your O-ring as well. Make sure that everything is compatible with each other before you start up your water system again.

Step 6: Check The Filter Again and Repeat Process

Eventually, the filter that you installed will be used up as well. This means that more sediment and contaminants are getting filtered out of the water than what can fit inside the tank itself. You need to check your filters every few weeks using a TDS (Total Dissolved Solids) meter to see if they are getting used up.

This is a process that can be repeated until you notice that the TDS levels have gone down significantly from what it was before. When this happens, then the system is ready for another replacement filter to be installed.

Step 7: Check The Reverse Osmosis System

It is also a good idea to check the rest of your reverse osmosis water treatment system. This will include making sure that all of the pipes that are connected to it are still in good shape and unclogged. If you have any concerns about how well your system is working, then you should contact a technician who can come out and provide you with a diagnosis.

Step 8: Enjoy Your Fresh Water

That’s all, Now you can turn the valve back on and enjoy some great tasting water straight from your home’s reverse osmosis filter. This is one of the most important steps to take when you are busy with life but want to make sure that your water is clean.

How do you know that your RO filters need replacements?

Here are the following situations that should notify you about changing the RO membrane filter.

  • Your TDS meter shows a higher level than what is considered normal for your water. Normally, when leaving the tap open and waiting a while to see how long it takes for the water to get cold if it goes down to about 35 ppm or lower, then this could mean that your RO membrane is due for changing.
  • What that TDS meter shows is the number of minerals in the water, which could be causing your body harm if they are not removed before you drink it. 35 ppm is about halfway between safe and unsafe levels, so call a professional water treatment company to come out and inspect your system before anything bad happens.
  • What you may start to notice is that it takes longer for the water to get cold, or there could be some discolored build-up around the tank or hoses of your RO system. There will also likely be a strong chlorine-like smell if something is wrong with your filters. When this occurs, you need to contact an experienced professional who can come out and check your filters. These are all signs that something is wrong, so you need to act fast to make sure that you don’t run into any problems.
  • The great thing about a reverse osmosis water system is that it has an automatic shut-off function built-in. This means that if there is a problem with the filters, such as a leak or something else that prevents the water from passing through, then it will stop working and prevent further damage. This can save you a lot of money by preventing your pipes from becoming damaged from lack of water flow.


When is the ideal time to change a reverse osmosis filter?

The best time to replace your filters is after you have been using them for about six to eight months. This will keep you from having to buy more filters too soon and it will also make sure that your water stays fresh and tasty even with repeated use throughout the day.

When replacing your filters, it is also a good idea to keep an eye on the pressure gauge that comes with your reverse osmosis system. Sometimes, there will be some fluctuations in this gauge and you need to be ready for this change before replacing your system’s filters as this could mean there are many problems with the functionality of your water filter unit.

Are there any precautions that I should use when replacing a reverse osmosis filter?

Replacing the filters in your reverse osmosis system can be quite easy to do. You just need to make sure that you follow all of the steps listed above and you will be able to easily change the filters without breaking anything or causing other big problems.

One thing that you should avoid, though, is using reverse osmosis filters from other brands or systems. This can cause your O-ring to break or it will not fit in the proper location on your filter with ease. You should only use a replacement filter that has been made for your system and not one that was created by any other source.

Final Thoughts

Reverse osmosis systems are typically a smart investment for your home, especially when you need to take care of lead or chemical contamination that is present in your water. These filters are also useful because they don’t cost a lot of money or require special tools to work on them. You can change the filter yourself and remove most of the contaminants that are present in the water.
